The ipNetToPhysicalPhysAddress indices match the ifIndex scheme used in the ipv6IfTable. To get the textual representation of the interface names, use ipv6IfDescr. For example:
snmpwalk -c public -v 2c localhost ipNetToPhysicalPhysAddress IP-MIB::ipNetToPhysicalPhysAddress.2.ipv4."192.168.10.17" = STRING: 24:77:3:87:b8:68 IP-MIB::ipNetToPhysicalPhysAddress.8.ipv4."127.1.1.2" = STRING: 0:1:23:45:67:0 IP-MIB::ipNetToPhysicalPhysAddress.8.ipv4."127.1.1.3" = STRING: 0:1:23:45:67:1 IP-MIB::ipNetToPhysicalPhysAddress.16.ipv4."10.11.113.22" = STRING: 0:c:29:c3:86:f1
snmpwalk -c public -v 2c localhost ipv6IfDescr IPV6-MIB::ipv6IfDescr.1 = STRING: lo IPV6-MIB::ipv6IfDescr.2 = STRING: eth0 IPV6-MIB::ipv6IfDescr.3 = STRING: eth1 IPV6-MIB::ipv6IfDescr.4 = STRING: eth2 IPV6-MIB::ipv6IfDescr.5 = STRING: eth3 IPV6-MIB::ipv6IfDescr.8 = STRING: tmm0 IPV6-MIB::ipv6IfDescr.16 = STRING: external
eth0 is the mgmt interface. tmm0 is an internal interface used by TMOS. external is the name of a VLAN (and the only defined VLAN) on this system.
